Dotenv: [Feature Request] Allow variables in .env

[mattcdavis1]

It would be nice to be able to use variables in the .env file similar to Laravel.

PROTOCOL=https://
HOST_NAME=dev.mysite.com
HTTP_PORT=443
APP_URL=${PROTOCOL}${HOST_NAME}:${HTTP_PORT}

Is this what you're wanting? https://github.com/motdotla/dotenv#what-about-variable-expansion

[mattcdavis1]

@zenflow - it seems similar but the variable-expansion you referenced seems to be limited to machine variables rather than other variables in the same .env file.

[zenflow]

The example .env file in that project seems to indicate you can use variables from the same .env file (e.g. look at MONGOLAB_USER). If you tested and it doesn't work, I'd open an issue there.

hmm - i looked at that .env example previously and did not see an example of re-using a variable that was defined in that same file. i'll check again.

[mattcdavis1]

ok - yeah i see now. the MONGOLAB_USER you referenced. thanks!
